I ran a VL475 from 1986 until 1996. 17.5' Kevlar hull with a Mariner 150 jack plate 24 prop. Motor Guide 24v tm. Hit 70 on slick water. Didn't handle big water well but was fast and fun. I used it as a Lake Okeechobee guide boat until I got a 20' HydraSports DV220. Earl Bentz was running HS back in mid 80s and then he started Stratos
